1. What happens when a protein solution is at its isoelectric point?
The net charge on the protein will become neutral resulting in decreased tendency of the protein to hydrogen-bond with water. Therefore, the protein becomes least soluble at its isoelectric point.
2. State 2 proteins that are responsible in the formation of an elastic dough.
a) Gliadin
b) Glutenin
